  "abstract": "<p><strong>Study area</strong></p>\n\n<p>The study area in Eigenbilzen is situated in the agricultural zone east of the locality of Eigenbilzen, in the province of Limburg, Flanders, Belgium. The flights picture a wheat field where damage by wild boar is apparent.</p>\n\n<p><strong>Data collection</strong></p>\n\n<p>Data were collected by the <a href=\"https://www.inbo.be/en\">Research Institute for Nature and Forest (INBO)</a> with a fixed wing drone Gatewing X100 in 2015 (2 flights). RGB data were acquired using an off-the-shelf Ricoh GR Digital IV camera, with the following image bands: 1: red, 2: green, 3: blue, 4: alpha channel. CIR (color-infrared) data were acquired using a NIR-enabled Ricoh GR Digital IV camera, with the following info bands: 1: NIR, 2: red, 3: green, 4: alpha channel.</p>\n\n<p><strong>Data processing</strong></p>\n\n<p>The raw data were processed to Digital Surface Models and orthophotos by INBO in 2015 using Agisoft PhotoScan Pro 1.0.4, a structure-from-motion (SfM) based photogrammetry software program.</p>\n\n<p><strong>Coordinate reference system</strong></p>\n\n<p>All geospatial data have the coordinate reference system <code>EPSG:31370 - Belgian Lambert 72</code>.</p>\n\n<p><strong>Files</strong></p>\n\n<ul>\n\t<li><strong>Raw flight data</strong>: images and logs collected by the drone during flight. These files are zipped per flight, with the date (<code>yyyymmdd</code>) and flight number (<code>x</code>) indicated in the file name (<code>flight_yyyymmdd_Bilzen_x.zip</code>).</li>\n\t<li><strong>Processed data</strong>: Digital Surface Models (<code>filename_DSM.tif</code>) and orthophotos (<code>filename_Ortho.tif</code>) stitched together from the raw data. The included flight is indicated in the file name (e.g. <code>20150728_Bilzen_1_DSM.tif</code>).</li>\n\t<li><strong>Ground control points</strong>: not applicable for this dataset.</li>\n</ul>\n\n<p><strong>Cloud Optimized GeoTIFF</strong></p>\n\n<p>The most efficient way to explore the processed data is by loading the <a href=\"https://www.cogeo.org/\">Cloud Optimized GeoTIFFs</a> we created for each processed file. Copy one of the file URLs below and follow e.g. the <a href=\"https://www.cogeo.org/qgis-tutorial.html\">QGIS tutorial</a> to load this type of file.</p>\n\n<ul>\n\t<li><code>http://s3-eu-west-1.amazonaws.com/lw-remote-sensing/cogeo/20150728_Bilzen_1_Ortho.tif</code> RGB</li>\n\t<li><code>http://s3-eu-west-1.amazonaws.com/lw-remote-sensing/cogeo/20150728_Bilzen_2_DSM.tif</code></li>\n\t<li><code>http://s3-eu-west-1.amazonaws.com/lw-remote-sensing/cogeo/20150728_Bilzen_2_Ortho.tif</code>&nbsp;CIR</li>\n\t<li><code>http://s3-eu-west-1.amazonaws.com/lw-remote-sensing/cogeo/20150728_Bilzen_1_DSM.tif</code></li>\n</ul>\n\n<p>See <a href=\"https://s3-eu-west-1.amazonaws.com/lw-remote-sensing/index.html\">this page</a> for an overview of public INBO RPAS data.</p>",
